[SOLVED] how to check for blank spaces in a text field???

[cluce]

does anybody know how to check for blank spaces?  I dont just mean blank, blank but actual spacebar spaces.  ive tried is_null and !isset and neither one works??

[per1os]

<?php
$textfield = isset($_POST['textfield'])?trim($_POST['textfield']):'';

if (empty($textfield)) {
     echo 'The text field is empty';
}
?>

 

Trim the data  www.php.net/trim

I am trimming the data which didnt work but I never tried the empty function.

isset() on a text field will always return true since the empty string is a legitimate value. empty() on the other hand, will return false if the value of the variable is equivalent to an empty string. So, empty() would actually return your desired results with or without trimming.
